Ensemble Klang’s The Big Loud Thing In honor of the 50th anniversary of the iconic Orkest De Volharding, the street orchestra of Louis Andriessen and Willem Breuker, Ensemble Klang presents a series of free pop-up concerts in which the music of De Volharding is central. Free-thinking, colorful and cooperative, De Volharding’s saxophones, brass instruments and rhythm section effortlessly combine contemporary music with jazz, pop and avant-garde. De Volharding is an icon in Dutch ensemble culture, it stood at the cradle of hundreds of works by leading composers, fascinates the public to this day and is a great source of inspiration for the next generation of artists. To honor this unique orchestra and its anniversary, Ensemble Klang, for whom De Volharding has always been a source of inspiration, is joining forces with musicians from Neo-fanfare 9×13. Together they perform five decades of the exciting Volharding repertoire in a series of pop-up concerts. The five pop-up concerts feature works by Louis Andriessen, Julia Wolfe, Hanna Kulenty, Misha Mengelberg, Steve Martland and many more.
